I only started watching in the tiebreak. Just cause he show boated initially and got a reprieve doesn't mean he can't show heart after that. If he hits the ball as hard as he can and makes it on big points then good for him. It's not like he hasn't done it before.
Sure, good for him. Let's not confuse it with heart or testicular fortitude, though.
Tiebreak was heart, but the return game was not.
